Google kuulutas p\u00e4rast kuut aastat projekti kallal t\u00f6\u00f6tamist v\u00e4lja OpenTitan avatud platvormi p\u00f5hjal valmistatud kiibi tootmise alguse. Kiipi toodab ettev\u00f5te Nuvoton ja see on t\u00e4histatud kui esimene OpenTitan elluviimine, mis on valmis kasutamiseks t\u00f6\u00f6s. Praegu on testimiseks v\u00e4lja antud proovipartii ja massilise tootmise k\u00e4ivitamine on plaanis selle aasta kevadel. <\/p>\n

OpenTitan on platvorm usaldusv\u00e4\u00e4rsete riistvarakomponentide (RoT, Root of Trust) loomiseks, mida kasutatakse seal, kus on vajalik tagada s\u00fcsteemi riistvara- ja tarkvaraelementide terviklikkus. N\u00e4iteks selleks, et kinnitada, et s\u00fcsteemi kriitilised osad ei ole vahetatud ja p\u00f5hinevad tootja poolt kontrollitud ja autoriseeritud koodil. Projekt pakub v\u00e4ljat\u00f6\u00f6tatud, kontrollitud ja usaldusv\u00e4\u00e4rset raamistikku, mis aitab suurendada loodud lahenduste usaldusv\u00e4\u00e4rsust ja v\u00e4hendada spetsialiseeritud turvakiipide arendamise kulusid. <\/p>\n

OpenTitan p\u00f5hised kiibid v\u00f5ivad olla kasutusel serveri emaplaatidel, v\u00f5rkaartidel, tarbeseadmetes, ruuterites ja asjade interneti seadmetes, et kontrollida p\u00fcsiprogramme ja laaditavaid komponente, genereerida kr\u00fcptograafiliselt unikaalseid s\u00fcsteemi identifikaatoreid (kaitse seadmete vahetuse eest), pakkuda turvalisuse teenuseid, kaitsta kr\u00fcptograafia v\u00f5tmeid (v\u00f5tmete isoleerimine juhtudel, kui r\u00fcndaja saab f\u00fc\u00fcsilise ligip\u00e4\u00e4su seadmele) ja pidada isoleeritud auditi logi, mida ei saa muuta ega kustutada. <\/p>\n

OpenTitan sisaldab RoT-kiipides n\u00f5utavaid loogikablokke, nagu avatud mikroprotsessor RISC-V (RV32IMCB Ibex) arhitektuuril, kr\u00fcptograafilised kooprotsessorid, riistvaraline juhuslike numbrite generaator, v\u00f5tmehaldur DICE toega, mehhanism kaitstud andmete salvestamiseks p\u00fcsivasse ja operatiivm\u00e4lu, kaitsetehnoloogiad, sisend-\/v\u00e4ljundbloke ja turvalise k\u00e4ivitamise komponendid. Seade pakub ka plokke standardsete \u0161ifreerimisalgoritmide, nagu AES ja HMAC-SHA256, rakendustega ning matemaatiliste tehete kiirendajat, mis on vajalik avatud v\u00f5tmete digitaalsete allkirjadega t\u00f6\u00f6tamiseks.

\"Alustati<\/center> <\/p>\n

Projekt on rajatud Google'i poolt, kuid edastatud mittetulunduslikule organisatsioonile lowRISC, mille j\u00e4rel liitusid arendustega sellised ettev\u00f5tted nagu Western Digital, Seagate, Nuvoton Technology, Winbond, Rivos, zeroRISC ja G+D Mobile Security. Projektiga seotud kood ja riistvara spetsifikatsioonid on avaldatud lisatud Apache 2.0 litsentsi alla. OpenTitanis kasutatavad lahendused tuginevad tehnoloogiatele, mida on juba kasutatud Google'i Titan kr\u00fcptograafilistes USB-tokenites ja TPM-kiipides, et tagada kinnitatud k\u00e4ivitamine. serverites<\/a> Google\u2019i infrastruktuuri ning Chromebooki ja Pixel seadmetesse. <\/p>\n

Erinevalt olemasolevatest Root of Trust'i rakendustest areneb OpenTitan kontseptsiooni j\u00e4rgi \"turvalisus l\u00e4bi l\u00e4bipaistvuse\", mis h\u00f5lmab koodi ja skeemide k\u00e4ttesaadavust ning t\u00e4iesti avatud arendusprotsessi, mis ei ole seotud konkreetsete tarnijate ja kiibitootjatega. OpenTitan on esimene turule toodud avatud rakendus Root of Trust'ist, mis toetab post-kvantmehanismi turvaliseks k\u00e4ivitamiseks, kasutades SLH-DSA (Sphincs+) digitaalsete allkirjade genereerimise algoritmi, mis on kvantarvutite purunemiskindel.
